The LTC6991HS6#TRMPBF is a silicon oscillator from Analog Devices' TimerBlox® family, designed to generate extremely long timing periods — from 29.1 µHz up to 977 Hz — using a single external resistor. It runs from a 2.25 V to 5.5 V supply and draws 135 µA typical.
It is ROHS3 compliant.
The LTC6995 series (e.g., LTC6995HS6-1#TRMPBF) is a higher-frequency sibling in the same TimerBlox® family and the same TSOT-23-6 package, but it covers a different frequency range — it tops out at 977 Hz as well but starts at a higher minimum. For the ultra-low-frequency range of the LTC6991, there is no direct pin-compatible second source; the LTC6991 is the only TimerBlox® part that goes down to 29.1 µHz.
The output frequency is set by connecting a single resistor between the SET pin and ground. The resistor value determines the period according to the formula in the datasheet. No software or external clock is required.
